Claims

C1strongest claim

With the 102 months of data collected by DAMPE, we show that the Fermi bubbles are detected at a significance of ∼26σ and identify a GeV excess in the direction of Galactic center at ∼7σ confidence. Both spectra and morphology are consistent with those observed by Fermi-LAT and the GeV excess component can be interpreted by the dark matter annihilation with a mass of ∼50 GeV and a velocity-averaged cross section of ∼10^{-26} cm³ s^{-1} for the χχ → b b-bar channel.

C2weakest assumption

The assumption that the observed GeV excess is produced by dark matter annihilation rather than unresolved astrophysical sources, and that the background subtraction and morphology modeling do not introduce systematic biases that mimic the excess signal.

C3one line summary

DAMPE independently detects the Fermi bubbles at 26 sigma and the Galactic center GeV excess at 7 sigma, with the excess spectrum and morphology matching Fermi-LAT and fitting a 50 GeV dark matter particle annihilating to b quarks.
